View Full Version : Power Mac G5 Processor Problems

Jun 28, 2011, 11:29 PM
I've got a Power Mac G5 Dual 2.0ghz though I'm having some problems with one of the processors. It seems that about 85% of the times I boot the computer Hardware Monitor and About this Mac only shows one processor. There's still a few occasions that when I turn it on both processors are running and operational but most of the time only one is detected. Is this a sign of a bad processor or bad motherboard? Or is it a hardware problem? I've tried reseating the processor about 4 or 5 times now without any difference. The second processor just seems to kick on whenever it feels like it, really.

Any help would be appreciated.

Dang, that's what I was afraid of. I'll try the re-install that I planned on doing today and if that fails at least I know what the problem is then.

The procs may just need to be reseated. I rebuilt a G5 that was reported to be not booting and completely tore it down, rebuilt it and reseated the processors and good as new.

Is it a LCS (Liquid Cooled/Cooling System) G5 model? If so, sometimes that can leak and cause all sorts of chaos, too unfortunately.
